Be it known that I, THOMAS ALLEN DAVISON, a citizen ofthe United States,resi'dingatKellerville, in the county of Adams and State ofIllinois, haveinvented certain new and useful improvements in Thill and Pole Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference tail view of the wrench.

In the drawings, A represents a thill, and B the front axle of a vehicle. I: make a clip, O,

of the right-angled plate 0, having on the end a hole in the long arm of-plate c, and its head is preferably countersunk therein. Thus it will be seen that the clip 0 can be very easily -H by a bolt and nut, h h".

G is the thill-iron, having an open eye, 9,

and H a bottom plate, which has the curved bearing h for the pivot c, which is integral with the plate 0. At its front end the thilliron is connected with the thill A and plate The thill-iron has a tenon, g, which is threaded, passes through the rear end of the plate H, and is secured by a nut, Thus it will be seen that by simply unscrewing the nuts [L2 the plate H may be quickly detached and the thill taken off.

\Vhat I claim as new, and desire to protect' by Letters Patent, is-

1. In thill-couplings, the combination of the right-angled plate 0, carrying the pivotc, the hinged cap a", the top-threaded post 0 having its head countersunk in the plate, and the nut E,let into the cap, as .shown and described.

2. The thill-iron G, open at the bottom and provided with a screw-tenon, g, and the plate H, having the bearing h, in combination with the bolt h and the nuts h", substantially as shown and described.

3. The hinged cap 0, having grooves c, in combination with a sliding cover c, as shown and described.

In testimony whereof I aifixmy signaturein presence of two witnesses.
